A map for exploring

How the ideas connect

The four labs show different forms of learning. Use this map to choose a question, then test it in a lab.

Four ways to explore learning

01Perceptron

How does one unit decide?

A handwritten digit becomes a set of signals. The learner weighs them, makes a decision and adjusts when it is wrong.

Given
Examples with right answers
Changes
Weights and a decision threshold
Look for
A mistake that changes the next decision
Try Perceptron Lab
02Weather

What can examples reveal?

Compare a model taught with right answers against groups formed using measurements alone.

Given
Studied days, with or without answers
Changes
A fitted curve or group centres
Look for
How the two modes differ
Try Weather Lab
03Student

What do layers add?

Several learning units work together to recognise more complicated patterns in an invented class.

Given
Student examples with grade bands
Changes
Connections between units
Look for
Studied versus unseen results
Try Student Lab
04Rink

Can practice replace answers?

A skater chooses actions, sees the consequences and gradually learns which moves are worth trying.

Given
A rink and points for outcomes
Changes
The skater's memory of actions
Look for
How its best play changes
Try Rink Lab

Carry one question across labs

Notice what changes

01

Where does feedback come from?

The first three labs can use right answers. In the Rink Lab, the skater receives points after acting.

02

What counts as learning?

Watch a weight, a curve, a group centre or a memory map change as the learner gets more experience.

03

Will it work on something new?

Compare studied and unseen examples in Weather and Student. In Rink, change the goalie or the rink and retrain.
